Manga debuted in February 2021
Sakamoto launched in February 2021. The manga’s fourth compiled book volume shipped in Japan on May 31.
The “adoration comedy” manga follows a little girl hero and the strongest Demon King. The Demon King has defeated every warrior he has come across, but when a weak little adventurer girl appears before him, he meets his match.
Sakamoto launched the Fairy Tail: Happy’s Heroic Adventure (Fairy Tail: Happy no Daibōken) spinoff manga on Kodansha‘s Magazine Pocket manga app in July 2018, and ended it in April 2020. Kodansha Comics is releasing the manga in English digitally.
